Just got new version 1.2 from the app store. All is well again. Big re-thx.

Excellent -- thanks for this and again, good luck for the remaining work on the thesis!

@AdamWright thanks and very luck with the thesis! (If necessary, you could always open-source the app, which I'll presumably come to like again :)

@AdamWright too bad that you apparently have not been able to look into this (so far). It's still an issue e.g. on iPhone 5 under iOS 6.0.1. It's probably easy too solve (top of crashed thread's core dump reads: EXC_BAD_ACCESS ... [UIScrollView removeFromSuperview] + 60 ... __CFRunLoopDoTimer + 270. Haven't been (able to) use(d) the app in a while now and so it has lost quite a bit of its shine (for now).
